Title: Digital subscriber line device test system
Inventor: ISE NOBORU
IPC: H04M3/26
Filed: 1990-08-17
Abstract: PURPOSE:To conduct a test only by operation from a subscriber side by providing a subscriber-side network terminating device with a check means for data sent from an exchange after command transmission and a digital subscriber line device with a means which sends the data out to a subscriber line on command detection. CONSTITUTION:When a test switch 110 is turned on, the subscriber-side network terminating device NTE10 generates an actuation signal by an actuation signal generating means 11 and sends the signal to the digital subscriber line device DLC15 and a test command sending means 12 is actuated a specific time later to send a test command to the DLC15. The DLC15 once detecting the test command actuates a sending-back means 18 to send data back in a down direction as it is or process the data and send the resulting data when the data is received successively to the test data. The NTE10 checks whether or not received data is predetermined data by the check means 13. Consequently, the test is conducted only by the switch operation from the NTE side.

Abstract: PROBLEM TO BE SOLVED: To shorten molding time for a wooden hard board molding and to reduce molding cost. SOLUTION: For molding a laminate prepd. by laminating raw materials such as a fibrous material and a powdery material into a specified thickness into a specified shape, the raw materials are sucked between both molds 11 and 12 for molding by the action of negative pressure and are laminated on the mold face 11c of the bottom mold 11 to form a laminated body B and then, suction of the raw materials is stopped and the laminate B is compression- molded between both molds 11 and 12 to prepare a base material. As the laminate B is formed on the mold face 11c of the bottom mold 11, the formed laminate B has a shape along the mold face 11c and the moldability is improved and failures are decreased and the productive efficiency is improved.

Title: Ink jet printing head
Inventor: KOIZUMI YUKIHISA
IPC: B41J2/05
Filed: 1989-08-24
Abstract: PURPOSE:To protect against cavitation damage by providing a constitution in which a liquid flow path communicates with a jet nozzle, and a recessed part with a thermal element installed at the bottom has an asymmetric cross section with respect to the thermal element. CONSTITUTION:Air bubbles are generated by connection of a printing signal to a thermal element 2 and ink droplets are sent flying to recording paper from a nozzle 5 by the pressurized bubbles applied to ink 6. Subsequently, the bubbles 7 disappear rapidly due to the disappearance of the printing signal applied to the thermal element 2. When the bubbles are generates, these grow almost upward along the walls 3, 4 at a recessed part to eject the ink 6. However, when the bubbles disappear, these become small rapidly with the ink moving from the nozzle 5 and ink reservoir sides. The nozzle 5 side allows the ink to move more rapidly due to lower liquid resistance, and the whole bubbles disappear along the tapered wall. Thus cavitation damage is dispersed and the subsequent damage to the thermal element 2 is minimized.

Title: Material strength tester
Inventor: KASAI KENICHI
IPC: G01N3/18
Filed: 1984-10-19
Abstract: PURPOSE:To dispense with a cooling piping by providing a load detection mechanism in series to a test piece while a high pressure cool water as load generation source is used to cool a detecting section. CONSTITUTION:When the pressures in pressure chambers 10, 11 and 12 are equal, first and second pistons 8 and 9 will not move. But when the working pressure from a feed tube 20 is changed to make the pressure of the pressure chamber 12 lower than those in the pressure chambers 10 and 11, the pistons 8 and 9 moves downward while they do upward when done higher than those thereby applying a tensile load and a compression load to a test piece 23. Therefore, the application of a repeated load to the test piece 23 is made possible by varying the pressure of the pressure chamber 12 with the time. The load on the test piece 23 is detected with a load detector 24 provided in series to the test piece 23 and drawn out through a signal fetching shaft 26. The pressure chamber 10 having the test piece 23 arranged therein is hot at a high temperature while the detector 24 is positioned on the low temperature side. Heat from the high temperature part is confined to heat conductivity with the piston 8 and the cooling of the detector 24 becomes possible by a fluid flowing into the pressure chamber 11 from a high pressure feed pipe 15 thereby eliminating the need for cooling and pipings particularly.

Abstract: PURPOSE: To correctly identify a specified cylinder of an internal combustion engine according to a single circuit signal by operating the time ratio of reference position, and monitoring the change of the continuous two sections to conduct the normalizing processing according to the time ratio of a designated section. CONSTITUTION: A micro-computer 10 measures the time T during the rise of a signal of a first reference position and the time (t) during the fall of a signal from signals input through an interface circuit 9 from a rotation signal generator 8. Concerning the respective sections, the ratio t/T of the time T to the time (t) is computed. A difference between this time value of the ratio and the preceding value is divided by the preceding value to obtain an operation value α. This operation value α is compared with a designated value β, and if α>=β, the next positional signal is determined to be a second positional signal corresponding to a specified cylinder, and it proceeds to the next step. If α<β, the next positional signal is determined to be a first positional signal corresponding to each cylinder.

Filed: 1987-09-01
Abstract: PURPOSE:To obtain a stronger magnetic field of an arbitrary shape and to eliminate the leakage of magnetism to an exterior by mounting a magnetic shield layer of a superconducting substance inside a superconducting magnet cryostat. CONSTITUTION:A cryostat for a superconducting magnet is formed of a superconducting coil 1, cooling medium 2 for cooling the coil to a critical temperature or less, a heat insulating vessel 3 for holding temperature, and a magnetic shield layer 4 of a superconducting substance at a position cooled by the medium 2 inside the vessel 3.

Title: Optical transmitter
Inventor: TAKAHASHI HIDETO
IPC: H04B10/564
Filed: 1990-08-20
Abstract: PURPOSE:To hold an optical output of an optical fiber constant even if a tracking error exists by controlling a bias current from a driving circuit based on a sensed result of a photodiode for sensing an output of a rear light of a laser diode and a resistance value of a thermistor for sensing a peripheral temperature of the diode. CONSTITUTION:When a peripheral temperature of a laser diode 11 rises, an optical output 113 of an optical fiber 12 is increased. In this case, a resistance value of a thermistor 44 of an automatic optical output controller 4 is reduced, and a potential of a non-inverting input terminal of an operational amplifier 41 is reduced. Thus, since the base potential of a transistor 45 is lowered, its collector current is reduced. Accordingly, the bias current of the diode 11 is reduced, and its output is reduced. Accordingly, if the output of the diode 11 is reduced in response to its peripheral temperature by suitably selecting a constant indicating the ratio of variation in the resistance value of second thermistor 44 with respect to its temperature, the output 113 of the fiber 12 can be maintained constant irrespective of the peripheral temperature of the diode 11.
